What's in this update
- When message is played in FSK mode a WinKey commands possibly contained in message (except PTT ON/OFF) are filtered out. It allows playing of "any" message in both CW and FSK modes.
- Added possibility to insert extra FIGURE SHIFT, extra LETTER SHIFT, BLANK and BEL characters to FSK Message. Also PTT ON and PTT OFF commands work in FSK mode.
- New keyboard mode switching: When MK is connected router can force one of CW, FSK or VOICE keyboard mode or can set "manual" to allow user switch modes by CAPS key. When MK is disconnected user can manually switch between CW and FSK modes (VOICE mode cannot be used without router).
- bug fixed: When in CW mode the ALT key (or CTRL in versions older than v2.7) was pressed without entering the new number, keyer stoped respond to keyboard events.
- bug fixed: CK and DK now return correct value of CTS.
- bug fixed: Small bug related to "USB disconnect timer" was fixed.
- Migration to WinAVR 20060125
- Note: Since this version the firmware is updated consistently with "mok" firmware for MK2R.
